While importing the Harry Potter Audiobook i realized that it looks ugly to have Tracknumbering starting with '01' and ending '108'. While most players will get along with this i wondered wether i can extend the tracknumbering to start with '001' in such situations conditionally?

Rather then having clutter on filesystem in this special situation with Harry Potter Audiobook i tried this to remove conditionally the Tracknumber, but it dont work out: albumtype:Audiobook: Hörbuch/$albumartist/%ifdef{year} $album%aunique{}/%if{$tracktotal < 100,$track,!$track} $title
